Composition of the Cell Membrane & Functions (pg 182)
The cell membrane regulates what _____ and ______ the cell
and also provides ____________ and ___________. The composition
of nearly all cell membranes is a ________________ sheet called a
________ _________. The lipid bilayer gives cell membranes a
_________ structure that forms a ________ barrier between the
cell and its _____________. Most cell membranes contain ________
molecules that are embedded in the _________ _______. The
proteins form _________ and ________ that help to move material
across the cell membrane. Particles move constantly and the most
common is diffusion, which does not require _______ and particles
move from an area of ________ to _________.
*Correctly color code and identify the name for each part of the cell
membrane.

Energy Requiring (p188)
One type of _________ transport which uses energy is called the
sodium potassium pump which helps muscle cells contract. This pump
uses ___________ to move ions __________ the concentration
gradient. The protein that is used to pump the ions through is called a
____________ protein and it changes its __________ to move the
ions across the cell membrane. Label and color the carrier proteins
red and the ions passing through (Na) green.
